Under the Revised Dengue Case Classification (WHO 2009), dengue with 'warning signs' includes all of the following EXCEPT:
- A Persistent vomiting and abdominal pain
- B Clinical fluid accumulation (pleural effusion, ascites)
- C Mucosal bleeding and liver enlargement >2 cm
- D Rapid breathing and declining platelet count from 100,000 to 80,000/mm³ ✓
Explanation
WHO 2009 dengue classification identifies 'warning signs' that predict severe dengue: abdominal pain/tenderness, persistent vomiting, clinical fluid accumulation, mucosal bleeding, lethargy/restlessness, liver enlargement >2 cm, and increase in haematocrit with rapid decrease in platelet count. A platelet decline from 100,000 to 80,000/mm³ alone with rapid breathing does not constitute a warning sign — rapid breathing is not listed among the warning signs. The critical platelet threshold is typically a rapid fall concurrent with haematocrit rise suggesting plasma leakage.
